OK. I have added setlocale(LC_CTYPE,"") to init_locale().
I also added Allin's pre-validation of strings to see if they conform
to UTF-8. The test doesn't really prove the string is UTF-8, but I
can't think of any non-contrived cases where this would be a problem.

Neither of these patches are strictly speaking necessary. The same=20
result could be accomplished by putting "set encoding locale" in
~/.gnuplot.  But having a more consistent initial state for the program
will I hope reduce the number of confusing bug reports.

This should also resolve bug=20
#1834525 'utf8 encoding not working in pdfcairo under C locale'
